You can upload as many lines as you wish, however more lines will take more time and every web browser will have its limits on the maximum number of lines (hence circles drawn) before things slow to a halt. We’ll then group the data based on its distance in order to perform a segmentation analysis. We’ll draw a circle around the point using a user-specified distance. In this tip, we’re going to look at visualizing geospatial data using the distance from a specific point on a map. To do this you must format your points using the convention of latitude,longitude,radius per line where latitude and longitude are in decimal format and radius in km. Visualizing the radius around a point on a map. The CSV option allows you to upload bulk points to the map. These features may be added later depending on feedback. Line thickness (you can change this once it is loaded into Google Earth) Note: We scale the area of the circle based on the population. Construct the circle for each value in citymap. First, create an object containing LatLng and population for each city. Line colour (you can change this once it is loaded into Google Earth) This example creates circles on the map, representing populations in North America. Shading colour (blue only, but you can change this once it is loaded into Google Earth) You can then open the KML file in application such as Google Earth

You will probably need to scroll down the page to find this!Īfter a short delay, the KML file with download The procedure to Export to KML is as follows:ĭraw one or more radii on the map as you see fit You need to have a radius displayed on the map before the output will work. You must have Google Earth installed (or another application capable of importing KML files). You can now export all the drawn radii on the map to Google Earth for improved display and printing. This URL can be sent to anyone if you wish to forward it on. Use the "URL to last radius" text box to find a URL that will show the most recent radius on this page when opened in a web browser. You can use the button to erase all markers and radii and start again. Ĭlick as many times as necessary to draw multiple circles.
